PECO To Trim Trees In West Vincent

PECO Invests $3 Million in Preventative Tree Pruning in Chester County

Project to improve electric service reliability for more than 45,000 customers

(January 10, 2013) -- PECO is investing about $3 million in preventative tree
pruning along 405 miles of aerial electric lines in Chester County to improve
electric service reliability for more than 45,000 customers. Work will begin
in early January and continue through May. Preventative pruning around aerial
power lines is vital to providing reliable electric service since vegetation
causes about one-third of all electric outages.

Pruning will be performed in the Townships of Charlestown, East Caln, East Goshen,
East Nantmeal, East Whiteland, Tredyffrin, Upper Uwchlan, Uwchlan, Wallace,
West Goshen, West Pikeland, West Vincent, West Whiteland and Willistown, and
the Borough of Malvern.

"Our goal is to reduce the frequency of tree-related outages and keep the lights
on for our customers," said Alex Brown, manager of Vegetation
Management. "Preventative maintenance programs like tree pruning and
other vegetation management play key roles in providing the safe and reliable
electric service our customers expect."

In 2013, PECO will invest approximately $33 million in its vegetation management
program, which includes tree pruning and other vegetation removal around approximately
2,700 miles of aerial power lines on the electric distribution and
transmission system across the service territory. The program also involves
annual patrols of the system and pruning or clearing on a cyclical basis.

PECO's vegetation management crews are trained in proper arboricultural pruning
techniques, which are defined in the American National Standards Institute
(ANSI) A300 Standard. This standard takes into account the type and location
of the tree in relation to the overhead wires and the health of the tree.
PECO notifies property owners prior to work beginning in each community.
Areas where line clearance work is completed experience fewer outages and a
significant improvement in electric reliability.
